Math::BigInt module in Perl provides objects that represent integers with arbitrary precision and overloaded arithmetical operators.
binf() method of Math::BigInt module is used to create a new object with value infinity and if used on an existing object, it sets it to infinity.
Syntax: Math::BigInt->binf()
Parameter:
plus or minus: to set the sign of infinity as ‘+’ or ‘-‘Returns: object with value inf
Example 1:
#!/usr/bin/perl # Import Math::BigInt module use Math::BigInt;
# Create a BigInt object $x = Math::BigInt->binf();
# Object created with binf() print("$x\n");
# Create a BigInt object $x = Math::BigInt->binf('-');
# Object created with binf() print("$x");
|
Output:
inf -inf
Example 2:
#!/usr/bin/perl # Import Math::BigInt module use Math::BigInt;
# Specify number $num = 78215936043546;
# Create BigInt object $x = Math::BigInt->new($num);
# Object before function call print("Before function call: $x\n");
# Calling the function $x->binf();
# Object after function call print("After function call: $x");
|
Output:
Before function call: 78215936043546 After function call: inf
Example 3:
#!/usr/bin/perl # Import Math::BigInt module use Math::BigInt;
# Specify number $num = 78215936043546;
# Create BigInt object $x = Math::BigInt->new($num);
# Object before function call print("Before function call: $x\n");
# Calling the function with '-' sign $x->binf('-');
# Object after function call print("After function call: $x");
|
Output:
Before function call: 78215936043546 After function call: -inf
